There is a lot to appreciate about these handblown glass tumblers. They're created in Aomori Prefecture in northern Japan by highly trained artisans who are working with sophisticated techniques. They use incredible precision to make these glasses because they are working with furnaces that heat up to 1500ºC to molten glass. You'll notice the smoothness in every single cup, which is achieved with a blowing iron and can only be accomplished by someone with refined skill and ability. The glass conveys a sense of seasonality, which will enhance all aspects of your life.
